Designed to resemble a spell book the mini laptop built by Hackaday member Calvin Nemo was created using TinkerCAD 3D printed outer shell which houses the Raspberry Pi Zero mini PC and other components. The general idea is that the outside panels of the “book” are made out of steel cut from the side panel…
Max Williams has just shared on Hackster.io schematics, PCB layouts, CircuitPython code via GitHub, BoMs, measurements and photos about his new open source modular HiFi amplifier. It uses an Adafruit ItsyBitsy M0 Express running CircuitPython to make great music. The preamplifier is made up of a number of connected components: MDAC attenuator (PCB, code): Controls the volume Input selector (PCB, code):…
Aptly named TWIST the open source environmental monitoring system is capable of sending tweets and collecting meteorological data thanks to its include gas, rain, light, temperature and humidity sensors. “Meet Tweeting Weather IoT Station aka TWIST – a DIY, Open-Source Environmental Monitoring and Meteorological Data Acquisition Platform. The purpose of TWIST is so that individuals…
YouTuber Electronoobs has just created an Arduino Nano multimeter device. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter is able to display voltage, resistance, current, and it’s also capable of reading capacitance and inductance. Power is provided by…
Youtuber Electronic Grenade, a DIY enthusiast, has created something truly impressive in the form of a mouse that doubles up as a full-fledged computer. Aptly called ‘The Computer Mouse’, the device has a small colour display, a slide-out keyboard, and of course, a fully-functional mouse which also forms the main body. The mouse is a…
SolidRun, a company focused on manufacturing Linux supported SBC and embedded boards, just announced the release of another addition to their Hummingboard series called the Hummingboard CBi. The new board features CAN port, serial ports and runs Linux on an i.MX6 MicroSOM processor. Debian, Yocto Project, BuildRoot, and OpenWrt stacks are available with a Linux 4.4x kernel,…
Using a Raspberry Pi mini PC the project published to the Hackster.io website shows the process of creating the Internet of Things breakout board from scratch to soldering the Sigfox modem from Wisol then sending data to Azure IoT Hub. The Breakout board is an open source PCB designed using the web software EasyEDA from JLCPCB. This board…
Using an array of 72 40kHz ultrasonic transducers to form standing waves of low and high pressure, the maker Julius Kramer has just created a 3d-printed acoustic levitator. 36 each are placed in the top and bottom shells of the device’s chassis. What’s interesting about Kramer’s build is that he does a great job illustrating how it works,…
Instructables user Sieuwe Elferink has just created a semi-autonomous kids’ four-wheeler. The Arduino powered Quad can steer itself within a set of lines, and stop for pedestrians and inanimate objects. For this project you will need the following materials: 3x TCRT5000 line sensor 1x HC-SR04 ultrasonic sensor 4x 5V relay 1x Windshield wiper motor 1x Arduino 2x tooth…
Maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors. The simplest version of this device, which he calls the ArdOsc, displays data on a computer…
OpenMinder is an open-source DIY project from Autogrow targeted to technology developers and for application with small growers. Released under a Creative Commons BY-NC-SA license, OpenMinder provides an open-source API used in conjunction with a Raspberry Pi HAT. OpenMinder™ is a product that you can build yourself, but more than that it represents where this…
Omzlo has won Kickstarter funding for a NoCAN platform for wired IoT home automation that connects sensor nodes to a Raspberry Pi. An Omzlo PiMaster HAT board mediates between the Pi and multiple, Arduino-compatible CANZERO boards that can connect sensors, lights, relays, and actuators for home and garden automation. The boards are connected via an…
